It's likely for perp pnl to oscillate and be settled in positive and
negative direction repeatedly. If the user's USDC balance is <= 0, every
settlement of negative pnl will increase borrows and cause loan
origination fees.
Over time the fees accumulated this way could be significant. Skipping
loan origination fees for borrows created from perp settlement avoids
that.
This gives us better compatibility with released anchor versions.
Instead of using AccountLoaderDynamic<MangoAccount>, we now use
a standard AccountLoader<MangoAccountFixed>. This will generally work
(except for load_init(), which is dangerous).
A new trait, MangoAccountLoader, provides load_full(), load_full_mut()
etc on the AccountLoader<MangoAccountFixed> to create accessor structs
that can read and write to the dynamic part of the mango account data.
While the flag is true, deposits that don't bring the account health
over the init threshold are forbidden. This makes it impossible for
users to drag out liquidation by continuously depositing tiny amounts.
Liquidation and perp pnl settlement may not bring spot amounts to
exactly zero. Having a small spot amount < 1 native token can otherwise
make the liquidation get stuck and not move one to the next phase.
* Client: Rework max_swap function
Determining the amounts at which the health function changes slope
becomes too difficult when serum3 open orders come in.
Instead, generally find the function's maximum and then work with that.
* max_swap: Add test for swapping into a trustless token

Liquidator, liqtest and rust client fixes
- Make rust MangoClient fully async
- Update and improve liquidation test setup scripts
- Update liquidator to use versioned transactions
- Update liquidator to use mango and jupiter account lookup tables
- Use jupiter v4 api to get versioned transactions
Perp liquidation is still not fully good. See discussion aboult perp_liq_pnl_with_token.
* dont do checks force close flag is used explicitly
